Analytical curves were obtained from 1.0x10(-6) to 8.0x10(-5)molL(-1) with a detection limit of 1.3x10(-7)molL(-1) by using the best experimental conditions, linear scan voltammetry at pH6, scan rate=60mVs(-1), and accumulation time=5min. The detection system performance was not interfered by other hair dyes and successfully used to determine the dye in tap water samples.2507-2514engTiTiO2 nanotube electrodeHair dyeTemporary dyes determinationAdsorption of dye on TiO2 nanoarraysArtigo10.1002/elan.201300322WOS:000330128800011Acesso restrito
